The Claim
In overweight and obese older adults with knee osteoarthritis, lower body weight is associated with a reduced peak knee abduction moment during walking, where each 1 kg (9.8 N) reduction in body weight corresponds to a 1.4% (0.496 Nm) decrease in this biomechanical measure, potentially reducing stress on the medial compartment of the knee joint.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If older adults who are overweight or obese and have knee arthritis lose 1 kilogram of weight, their knees experience less strain when walking — about 1.4% less stress per kilo lost — which might help protect the inner part of the knee.
See the scientific wording
In overweight and obese older adults with knee osteoarthritis, lower body weight is associated with reduced peak knee abduction moment during walking, with each 1 kg (9.8N) reduction in body weight linked to a 1.4% (0.496 Nm) decrease in this moment, which may reduce medial compartment stress in the knee joint.
What the research says
1 studyStudy: Weight loss reduces knee-joint loads in overweight and obese older adults with knee osteoarthritis.
The study found that when older adults with knee osteoarthritis lost weight, it reduced the stress on their knees when walking. For every 1 kg lost, the knee stress went down by 1.4%, just like the claim says.
